Is Joe Biden Eying A Run For The Presidency?

Vice President Joe Biden first ran for president in the 1980s, an up and coming young pol who was knocked out of the race. He tried again in 2008 before becoming President Obama's running mate. Now, he starts another term still number two. But at a weekend inaugural event, he declared, I'm proud to be president of the United States. His son corrected him, though one persistent question is whether the vice president may try one more run in 2016.
